What is Sustainable Yield?

Back

Only using enough of a resource to allow the resource to replenish itself within a certain time period.

Front

What would be the result of practicing sustainable yield according to the Once-ler's scenario?

Back

There would be a consistent amount of trees harvested per year and planting at least one tree for every harvested tree, leading to greater long-term profit.

Front

What type of growth curve is characterized by a rapid increase followed by a plateau?

Back

Exponential Growth.

Front

What is the number one cause of extinction and species endangerment?

Back

Habitat Disruption.

Front

What is a Trophic Cascade?

Back

When one species leaves an ecosystem and affects at least 2 other trophic levels and abiotic factors.

Front

Define Exponential Growth in ecological terms.

Back

A growth pattern where the population size increases rapidly over time, often represented by a J-shaped curve.

Front

What is the impact of Habitat Disruption on ecosystems?

Back

It leads to loss of biodiversity, extinction of species, and changes in ecosystem structure.

Front

What is the role of consumers in maintaining sustainable ecosystems?

Back

Consumers, such as bears and wolves, regulate populations of lower trophic levels to ensure resource availability.

Front

What does the term 'Trophic Level' refer to?

Back

The position an organism occupies in a food chain, which determines its role in energy transfer.

Front

What is the difference between Logistic Growth and Exponential Growth?

Back

Logistic Growth shows a population that grows rapidly but levels off as it reaches carrying capacity, while Exponential Growth continues to increase without limits.
